BUILDING BLOCK.

Application filed October 20, 1921. Serial N0. 508,998.

To all whom it may concern:

Be it known that SHIGEYUKI KANAMORI, a subject of the Emperor of Japan, residing at Gora Mashimos, 48 Kojimacho, Asakusaku, Tokyo, Japan, has invented certain new and useful Improvements in Building Blocks, which the following is a specification.

This invention relates to improvements in reinforced masonry wall structures of the type wherein the blocks or bricks are recessed for receiving coacting anchoring rods.

The invention has for its primary object to provide a. block made of stone, mortar, concrete, brick, or other suitable material of a rectangular shape and preferably of a length substantially double its width, the surface being marked or divided into eight substantial squares, while the body? is provided with a recess or hole in one of the squareson the inner face thereof, the recess or opening occupying a part or the whole area defined by such square for receiving the wall anchoring rods while at the same time the blocks may be used in connection with various methods of brick laying to in consequence ensure of the production of an efiective reinforced wall structure.

Other objects as well as the nature, characteristic features and scope of the invention will be more readily apparent from the following description taken in connection with the accompanying drawings and pointed out in the claims, forming apart of this specification.

This invention is clearly illustrated in the accompanying drawings, in which Fig. 1 is a perspective view of a portion of a wall structure in which the blocks are constructed in accordance. with this invention,

Fig. 2 is a top plan view of a usual form of block or brick,

Fig. 3 is the perspective view of a preferred type of block employed in the 'present wall structure,

Fig. 4 is a perspective viewof another form of block used in the wall structure when a stretcher layer is combined with header layers of the type of block shown in Fig. 3,

Fig. 5 is a perspective view of a slightly modified form of block of the type shown in Fig. '3,

Fig. 6 is a top plan view of another modification of the same type of block,

Fig. 7 is a top plan view of a further modification of the general type of block shown in Fig. 3,

Fig. 8 is a perspective detail of the type of block shown in Fig. 4 combined with headers of the type shown in Fig. 3, and

Fig. 9 is a perspective detail of superposed stretcher layers of the type shown in Fig. 3,

ig. 10 is a perspective detail of the type of block shown in Fig. 6 laid as headers and stretchers.

Similar characters of reference are em-. ployed in all of the above described views to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings there is provided an improved block which is formed of suitable material such as stone, concrete, mortar, brick or the like and is of a rectangular shape and of a length substantiall double its width, the upper surface of the lock being desirably divided or marked into preferably eight equal and substantially uare divislons or subdivisions A, B, C, D, F, 30 G and H, one of the inner squares C, D, or F being formed with a recess or opening 2. In ractice it has been found desirable to provide the recess at the square F or in the second square from the end of the block and preferabl: at the inner edge of the block so that it will be invisible in a completed wall structure. This recess or opening is desi ed to coact with one of a plurality of vertically arranged anchoring rods 3, the latter being adapted to extend throughout the height of the wall while owing to the size and shape of the blocks employed and the positioning of the recess the blocks may be laid in accordance with any method such as as the England, Flemish or common bond method of brick laying to insure of the 'completion of the effective reinforced masonry wall structure. In this connection it is desirable that the center of the recesses or we holes be at the center of the square or subdivisions or of the block in whlch the recess is provided. In addition it is also desirable that the size of the recess or opening be substantially twice the size of the diameter of the anchoring rods so that mortar may be placed about the rod within the recess for the protection of the rod against the action of weather ,in addition to securing a firm anchorage. As indicated in Fig. 1 there is shown a portion of a wall laid in accordance with the English bond method of brick laying of a'thick'ness equal to one and one-half the length of the brick or block and provided with the anchoring rods I for reinforcing purposes. In this arrangement it is to be observed that the blocks or bricks are of the type shown in Figs. 2 and 3, the former which is the uivalent of the regulation brick being use alternately in the header layers in conjunction with the recessed blocks. It is to be observed further that this method includes alternate header and stretcher layers, the recess 2 in the blocks 1 of the stretcher layers being positioned in alignment with the recesses 2 in the alternately arranged header bricks 1, such aligning recesses of course being are ranged about the rods 3.

In Figs. 4: and 8 there is a slightl modified form of block t employed. Thls block is of a size equivalent to the preferred form but in addition to the recess 2' equivalent to the recess 2 one of the outer squares such as B is provided with a further recess 2".

This type of block is used in the stretcher layers in combination with-header layers formed of blocks or bricks 1. This method of construction is desirable when it is deemed necessary to provide closely spaced anchoring rods.

Further modifications of the general type i of block 1 are shown in Figs. 5 to 7 inclusive in the block or brick 5 Fig. 5) instead of providing the recess 2, the block is provided in the same square F with a vertically and centrally opening or hole 6.

The block 7 in Fig. 6 is provided with a recess 8, the inner corners of which are restricted while the block 9 (Fig. 7) is provided in the same part of the body with a central opening 10 having a restricted portion 11 communicating with the inner edge which permits of the block body being inserted laterally about one of the anchoring rods without being placed over the top. This action of-course may be accomplished in using the blocks shown in Figs. 4: and 6 as well as in the preferred form.

By employing the present form of blocks or bricks in the production of reinforced the sides of the anchoring rods instead of over the' top thereof thereby increasing the speed of the brick layer in laying the bricks.

4. The manufacture of the recessed blocks or bricks may be simplified by merely employing small dies for adjustable connection with various portions of the mould of a conventional brick moulding machine thereby minimizing the cost of the bricks. In this connection it may be added that if desired the markings may be considered ima inary in which event the mould may be mar ed to ensure of the proper adjustment of the dies or the like or the correct positioning in the body of the brick.

It is believed that in view of the foregoing a further detailed description of the use of the blocks is entirely unnecessary. Likewise it is believed that the advantages will be readily apparent.

l-lavin thus fully described the invention what is c aimed as new and desired to be secured by Letters Patent is:

1. In a wall structure, in combination, vertically disposed anchoring rods extending throughout the height of a wall structure, a plurality of blocks each of which includes a body of a rectangular shape and of a length double its width, the surface of the block being marked to define eight equal subdivisions, one of the subdivisions on the inner edge of the block having a recess provided therein receiving and coacting with one of the anchoring rods, whereby a wall may be constructed of various methods of brick laying irrespective of the position of the rods.

2. Tnjan arrangement of the kind defined by claim 1 wherein the recess has an area double the'cross sectional area of the rod and wherein the center of such, recess coincides with the center of the subdivision substantially as and for the purposes set iorth. In testimony whereof I affix my signature in presence of two witnesses.
